Foundation pit assembly type steel trestle and construction method
The invention relates to the field of building construction, in particular to a foundation pit assembly type steel trestle and a construction method.The foundation pit assembly type steel trestle comprises a supporting column, a bearing beam, a bailey frame, a connecting piece, a transverse distribution beam and a bridge deck which are sequentially connected from bottom to top, a mounting groove is formed in the upper end of the bailey frame, and a flange is fixedly connected to the outer wall of the transverse distribution beam; the connecting piece comprises a supporting block, a positioning column, a sliding block and a clamping jaw, the supporting block is embedded in the mounting groove, a supporting groove is formed in the upper end of the supporting block, the positioning column is fixedly connected to the groove bottom of the supporting groove, the sliding block is slidably connected to the positioning column, the sliding direction of the sliding block is vertical, the lower end of the clamping jaw is hinged to the sliding block, and the upper end of the clamping jaw extends towards the positioning column to form a clamping groove; and the clamping grooves are used for embedding the flanges. The transverse distribution beam is positioned through the clamping grooves, the transverse distribution beam is clamped and fixed through the clamping jaws, welding and fixing are not needed, the construction efficiency of the steel trestle is improved, dismantling is convenient, dismantled accessories can be repeatedly used, material waste is reduced, and the construction cost is reduced.
本申请涉及建筑施工的领域，尤其是一种基坑装配式钢栈桥及施工方法，其包括从下至上依次连接的支撑柱、承重梁、贝雷架、连接件、横向分配梁和桥面板，贝雷架的上端设有安装槽，横向分配梁的外壁固定连接有挡边，连接件包括支撑块、定位柱、滑动块和夹爪，支撑块嵌于安装槽内，支撑块的上端设有支撑槽，定位柱固定连接于支撑槽的槽底，滑动块滑动连接于定位柱，滑动块的滑动方向竖直，夹爪的下端铰接于滑动块，夹爪的上端向定位柱延伸形成夹持槽，夹持槽用于供挡边嵌入。夹持槽对横向分配梁的位置进行定位，夹爪对横向分配梁夹持固定，无需焊接固定，提高钢栈桥的施工效率，便于拆除且拆除后的配件能够重复使用，减少材料浪费，降低施工成本。
